I rarely drive my 00 CLK 430 and my check engine light just came on. I just had it serviced and thought there was a glitch, b/c there was no malfunction listed on the computer. I disconnected the battery and the check engine light was gone. BUT- now the ABS and Check Brake light is on and is registering a message on the computer to "go to service center." So I did another battery disconnect.

I am sure this is another easy fix. But I can't figure it out.
I would appreciate any suggestions. Thanks.
